Seedlings- don't feed fer 1 week post emergance. Use seedling ratio days 7-14
Mid veg- days 14-? (two weeks before yer gonna flip)
Mature veg- the 14 days before flip ( building N levels to sustain stretch growth w/o early yellowing)
Transition- day of flip thru point where pistillate development achieves dime/ small cottonball size, stretch growth slows. Can be anywhere from 10 to 28 days.
Mature flowering- end of transition thru flush.
These are ABSOLUTE, STUPID, AND POTENTIALLY DANGEROUS OVERGENERALIZATIONS- you'll be making these calls based on yer plants, not my schedule.
You'll see exactly what they mean if you watch the plants, and why putting calendar dates on it just doesn't work.
I assume you understand that we have options on your time,
And we will ditch you in the harbour if we must-
But if it all works out nicely,
You'll get the bonus you deserve
From doctors we trust.
